Which of the following is recognized as a solvent in nail services?

Acetone is recognized as a solvent in nail services due to its ability to dissolve various substances, including nail polish and acrylics. This property makes it particularly valuable in the beauty industry, as it allows for the efficient removal of products that adhere to the nails.

In comparison, water is typically not classified as a solvent in this context because while it can dissolve some substances, it does not effectively remove nail products like acetone does. Alcohol, despite its use as a disinfectant, doesn't have the same solvent properties specific to the nail industry. Pine oil, while it has cleaning properties, is not generally used in nail services as a solvent. Thus, acetone stands out as the primary solvent utilized for its effectiveness in nail care and artistry.
